Abstract

A composite shipping base for supporting an appliance such as a washing machine is provided having a detachable sub-structure that can be added during the washing machine assembly to restrict the vertical and lateral movement of a centralized load of the washing machine during assembly, shipping and handling. A rigid bottom frame allows for the composite shipping base and appliance to move down virtually any form of conveyance and to be lifted or turned during the course of conveyance.

Claims

1. A shipping base for an appliance, the shipping base comprising:

a rigid bottom frame comprising four narrow, elongated opposing side members connected end to end to form a rigid support structure;

a bottom panel affixed to the bottom frame and having a top surface opposite the bottom frame, the bottom panel defining a center opening;

a narrow, elongated cross member extending between two opposing side members, the cross member having a width, the four opposing side members and the cross member having co-planar top surfaces on which the bottom panel can rest; and

a center insert resting on the cross member and detachably secured within the center opening and extending upwardly from the top surface;

wherein

the center opening is in vertical alignment with at least a portion of the cross member and has a width substantially greater than the width of the cross member.

2. The shipping base of claim 1 wherein the bottom panel has four corners, the shipping base further comprising:

a corner support affixed to the top surface of the bottom panel near each of the four corners.

3. The shipping base of claim 2 wherein:

each corner support defines a hole for receiving an appliance foot.

4. The shipping base of claim 1 further comprising:

means for preventing the center insert from rotating with respect to the bottom panel.

5. The shipping base of claim 1 wherein the center insert comprises a body having a non-circular horizontal cross-sectional area at its base that registers within a similarly shaped center opening to prevent the center insert from rotating with respect to the bottom frame.

6. The shipping base of claim 1 wherein:

the center insert comprises a substantially cylindrical body having a circular horizontal cross-sectional profile and at least one boss member extending laterally from a lower portion of the body that registers with the center opening to prevent the center insert from rotating with respect to the bottom frame.

7. The shipping base of claim 6 wherein:

the center opening includes at least one locating cutout; and

the center insert comprises a substantially cylindrical body having a circular horizontal cross-sectional profile and at least one boss member extending laterally from a lower portion of the body that registers with the at least one locating cutout to prevent the center insert from rotating with respect to the bottom frame.

8. The shipping base of claim 1 wherein:

the center insert has a body having a top surface and a bottom surface, the body defining a diametrically extending slot located in the bottom surface and configured to receive the cross member.

9. The shipping base of claim 1 wherein:

the top surface is configured to abut a centralized load located within the appliance.

10. The shipping base of claim 1 wherein:

the bottom frame is made of a rigid first material;

the bottom panel is made of a second material that is less rigid than the first material; and

the center insert is made of a third material that is different from the first material and the second material.

11. The shipping base of claim 1 wherein:

the bottom frame is made of wood;

the bottom panel is made of corrugated fiberboard; and

the center insert is made of a plastic foam material.
